A new method is described for recovering trapped CO 2 from polar ice cores. The ice is sublimed under vacuum, and H 2 O vapor and CO 2 are collected at appropriate cold traps. The application of this method to obtain CO 2 from a specific ice core, the conversion of that CO 2 to graphite, and the measurement of radiocarbon in the CO 2 are described in detail. The potentialities and problems of the method are discussed.
